Andrew Raingold, Executive Director of the Aldersgate Group, told Channel 4 News that Britain's economic growth will be further damaged by fresh confusion over windfarms and renewable energy.

He said: "The coalition's continued in-fighting about renewable energy is damaging growth. Business - the engine of growth - has been vocal about the competitive and economic advantage of a low carbon electricity supply in the UK."

"Renewable energy sources are a prudent investment: allowing the nation to hedge against future fossil fuel price volatility and benefit from greater long term cost certainty. These are at the heart of creating a positive environment for business."
